The present invention refers to a new de-` vice for clinical use for theintroduction, immersion and aspersion of medicaments in the form ofpowder, pomade, liquid, etc., in any 5 internal part of the body, theemployment of which represents distinct advantages of a practical order,inasmuch as its low cost and simplicity makes it` an instrument withinthe reach of everybody, apart from which it is of positive results.

In order that my application may be more comprehensible, I haveillustrated same with various figures, wherein:

the device.

' Fig. 2 is a longitudinal sectional view ot a variation of same. Y

Fig. 3 is a view of one ot the rods, forming a complement of the device.

Construction The construction comprises a depository with walls ot glass(a) and bases of metal.

(), into which is introduced the medicinal substance, either in the formof powder, pomade, liquid, or any other. In its lower part is found anozzle (c) to which is attached the end of a rubber tube (d) pertainingto a bulb of the same material. In this drum or deposit (a) (b), isinserted a canula (e), which may be straight, partially or totallycurved, and its end may be acute, obtuse, or intundibulitorm, accordingto the nature and object; said canula may have or not the division (7)which divides it in two (Fig. l), or it may be simple asv shown in Fig.2, the diameter and length varying according to circumstances, andmoreover, the canulas may have holes in their sides, in order that theintroduction ot the medicament may not only be effected by the end ofsame, but also laterally.

The canulas (e) and (e) and lany other which may be manufactured, arealways part and complement of the drum (a) (b), which may be constructedin accordance with Fig. l, that is, following the line of the canula(e), orftorming a right angle with same, or in any other convenientmanner.

The canula (e), Fig. 2, free of internal Fig. 1 is a longitudinalsectional view ot' division, has-as a propellant of the med-icament,aspiral (g'),'thread, spring, or rod, ,whichpushes or works in such amanner, that iteiiects the introduction of the medicament. y l 4.' Aswill be .'Se.en-, fthe various Qcanulas (e) '55 (ef), which m'ay'beconceived, areinter'- chan'gcable, and that which is'considered Ythe,i/nist'nvenient may be placed in thefdrum -`-`,I`he rods (j). (le),Fig. 3, arev complements of 'tlie'device,`the object .of which' will beexplained," and may beQ-of rigid or flexible material', otone sole'piece' (Ic) or divided oradopt the most convenient` form. The di- Yameter and length kof said rods may vary yaccording to the specialY'casesinwhich they are employed.` .y i

c fwofeagf The devicevf works as `follows:

On the canula (c) (e) being introduced it is necessary to avoid that thepus or liquid matter of the body, by automatic effect, may ascend bythecanula and obstruct or embarrass its working, and for this object Iinsert in the interior ot the canula (e) (e), the rod most adapted, besuch or (la), rigid or iiexible according to the case. The same is laterwithdrawn, to then eliect the introduction of the medicament. If it isdesired to use the canula (e), the bulb (cl) will be employed in orderthat the medicament in the form of powder which is generally found inthe drum (a) (b) may be pushed in a forward direction, being introducedby I the aperture (7L) and deposited in the part of the body which hasbeen reached by the canula. The air which has served to draw themedicament does not remain, nor is it lodged, f.

as happens with the usual apparatus, but returns by the other higherhalf of the canula (e), Fig. l, wherein the arrows indicate the passageof air, the latter being obturated in the lower part by the wedge (Z),which is removable.

IVhen it is not desired to employ air as the propellant, the thread orspiral (g) will be used, (Fig. 2), which in turn may be varied as toform, and it may take that of a simple rod, spring, piston, etc.,without this repre- F- senting a departure from the sphere of theinvention, the principal features of which are the method of propulsionwith the deposit of the medicament, and the interchangeability of thevarious canulas.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a device as described, a glass depository for the reception of amedicament, perforated metal caps for said depository, a tube passingthrough the perforations of said caps and said depository, said tubehaving a plurality of openings formed in its Wall and an aperture Withinsaid depository, a longitudinally extending partition dividing saidtube, anda means for expelling the medicament contained in saiddepository into a body.

2. In a device as described, a glass ldrum Afor the reception of themedicament, metal caps closing the ends of said drum and having centralopenings, a perforated tube extending through the openings in said capsand the drum, having a feed opening Within said d rum, a longitudinallyextending partition in saidtube, a nozzle formed With one of said capsadapted for engagement by a rubber. tube, and a bulb at the end of saidrubber tube for expelling the medicament in said drum into the cavitiesof a body, and means for elosin one end of said perforated tube, saidtube adapted for the reception of means preventing its obstruction.

In testimony whereof, Ialix my signature.
